The compartment C forms, acondensation or drip chaniber. From the compartment C the gas passesupwardly '-hiough the openin` G and the coil H which' terminates at itsupper end in the pipe Ileading to a valve head J. l" rom the valve headJ a 4pipe K leads to the bottom of'the upper compartment-B of thecarburetor. -The ac- -cess of gas to the 'pipe K ifs controlled bytheneedle valve L having a suitable thumbscrew M. The vvalve head J- alsoconnects with another needle valve N which is provided with a hose nipple and is adapted to be controlled by the thumb-screw 1 The uppervcompariment B of the carbureter is provided at its upper end with'acover R adapted to be screwed onto the top S.

it should be understood that it is intended tobc usedwith compressedair, oxygem'orj other gases .which are supportersot` combustion, andhasf'or its function the saturation or carbureting of such gases withthe volatile vapors -ofintlannnable liquid soasto generate aninflammable gas. Carburetors of this type are preferably used 4inconnection with oxygen gas, which-may be drawn from cylinders ofcompressed oxygen or from automatic oxygen generators.v lVhen connectedby tubing to the oxygen supply 'and as soon as the valve; on the oxygenapparatus is opened 'gas [lows into the pipe E to the coil E', thecondensation chamber C and the coil H to the valve head J, vfrom whichit may be admitted by the needle valve L to the pipe K leading to thebottom of 'the upper compartment B which has previously been filled withthe liquid lo the level of the outlet plugo. Upon passingl upthrough theabsorbent material' to the outlet cock'Q, the oxygen or air becomescarbureted or saturated so as to burn readily at 'the orifice' of asuitable burner, as' for cxample, the tip of a1 ordinary calcium lightjet.- This burner sl'euld beef a type adaptt receive a hollow plug ll"on which is mountl and a supporter of combustion such as oxy- 'densationmayl be' withdrawfn 'from timeftok erlftolbuin such mi,lture ofinflamn'mble Patent-@ 1 Dee. 30, 1913.

A f

Thistype of carbureter is V'adapted to be `used i'nconncction withburners consuming two gases or ini connection with a b urner adapted toconsume a single gas after it has become carbureted with the vaporot`the liquid usedr lVhen used in' connection with automaticjoxygen'generators which generate gas'froin the reaction between compounds 30such"asf.peroxid of sodium and water, there 'gis a certain amount ofWater vapor carried from vthe gen crateri-.Which would ordinarily tendtocollect in the-chamber containing the absorbent material. l In thecarburetor here-- I in described this vapor of water or other liquid,which may contaminate the supply of oxygen or air,condenses in the coilsE and H and is deposited in the condensation chamber C. This action isstimulated by .the cold 40 produced by the rapid vaporization of theliquid which. in practice causes a very Jmarked drop in temperaturewithin the carbureter.

If at any time it becomes desirable to change the absorbent material orfilling of the carbureter, the cover R may beremoved, which exposes anopening sulliciently large for that purpose. For the purpose of lillingthe carburetor with liquid it is only necessary to remove the hollowplug WV, which is provided at its upper portion with a hexagon c.

It is obvious that many forms of this invention maygE-be embodiedwithout using the exact construction shown.

I claim and desire to obtain by Letters Patent the following:

l. A carbureter comprising a carbureting cha1nber,a condensation chamberseparated therefrom, a pipe for gas to be carbureted leadingtortuouslythrough the carbureting chamber to the condensation chamber, apipe leading from the condensation chamber and having two branches, onebranch delivering outside the carbureter and having a. controlling valvefor @ducting gas uncarbureted, and the other branch opening into thecarbureting chamber below the normal liquid level therein, and a valvefor controlling the last said branch.

2. A carbureter comprising a carbureting chamber, a condensation chamberseparated therefrom, a pipe for gas to be carbureted leading through thecarbureting chamber to the condensation chamber, l a pipe leading 75from the condensation chamber within the carbureting chamber and havingtwo branches, one branch leading outside the carbureter and providedwitha valve foreducting gas uncarbureted and the other opening into thecarbureting chamber below the normal liquid level therein. I

3. A carbureter comprising a carbureting chamber, a coil thereinconnected to receive gas to be carbureted and in which the gas iscooled, a condensation chamber to which the said coil delivers, and a.pipe for conducting the gas from the condensation chamber back iiito-the carbureting chamber and delivering it nea-r the bottom thereof,'and a valve 90 for controlling the Aflow of such gas. .A

4. A carbureter comprising aycarbureting'; chamber, a coilthereinconnected to receive. gas to be carbureted and in which the as iscooled, a condensation chamber to whic the said coil delivers, and abranch pipe and valve for leading od some of the gas'after cooling andcondensation and Without carbureting.

5. A carbureter of the Aclass described, comprising a chamber havingcarbureting and condensation compartments, absorbent Inaterial placedWithin said carbureting com `A partment, a condensation coil within thecarbureting compartment and in communication with the condensationcompartment, means for conducting the flow oi" gas from ,condensationcompartment to the bottom of said carbureting compartment, a valvecontrolling and regulating said flow of gas to the bottom of carburetingcompartment and a secondary connection and valve for con-A trolling theflow o'the uncarbureted gas or other supporter of combustion.

In testimony whereof I have signed this specification in the presence oftwo subscribf ing witnesses.
